摘　　要：为探讨基于锚杆与钢结构的地铁竖井支护施工,结合青岛麦岛站3#竖井(位于麦岛站车站大里程端东南象限空地内)的实际情况,分析了锚杆和钢结构支护在地铁竖井支护中的应用方法以及要点,并通过竖井井壁初支结构净空收敛监测验证施工效果。研究结果表明:地铁竖井支护施工过程复杂,对施工技术要求较高,现场施工条件比较复杂,因此,仅凭单一的支护方式难以形成稳定的支护结构体系。采用锚杆和钢结构联合支护的方法,能够快速形成一个封闭、稳定的围护结构,以提升竖井的稳定性,为其他工序的顺利开展提供良好的条件。In order to discuss the subway shaft support construction based on bolt and steel structure,combined with the actual situation of Qingdao Maidao Station No.3 shaft,the application method and key points of bolt and steel structure support in the subway shaft support are analyzed,and the construction effect is verified by monitoring the headroom convergence of the initial support structure of shaft wall.The results show that the subway shaft support has strong complexity and technology,and the site construction conditions are complex.Therefore,it is difficult to form a stable support structure system with only one support method.The combined support of bolt and steel structure can quickly form a closed and stable enclosure structure to improve the stability of the shaft and provide good conditions for the smooth development of other processes.
